Implement I2C transaction filtering in pvrusb2
From: Mike Isely <isely@pobox.com>
Implement a rudimentary filter mechanism in the I2C adapter within the
pvrusb2 driver. It is possible now to interpose a filtering function
on a per-target basis. This function can intercept the requested
transaction and perform various manipulations on behalf of the
client. With this mechanism is also a filter inserted for wm8775 that
causes all probe attempts to the chip to always succeed (just return
success on probe attempts without touching the hardware). This neatly
solves the problem in the PVR USB2 hardware where we can't seem able
to probe the chip at all.
